The present invention relates to asuction controlled governor, and has for its prime object to provide a unit that occupies the space between the carburetor and the intake manifold, and has a suitable connection at this point for controlling automatically the suction therethrough. If desired, the governor units may be built in the carburetor.

Another very important object of the invention resides in the provision of a governor of this nature which is thoroughly efficient and reliable in operation, extremely sensitive to the lead load variations, and permits the use of all the available power of the engine at any speed. setting.

Another very important object of the invention resides in the provision of a governor of this nature which does not interfere with the speed or throttle action of the carburetor of the automobile up to the speed setting of the governor, so that, by opening thecarburetor governor wide, the governor will maintain an even speed.

A still further very important objectof the invention resides in the provision" of a governor of this nature which is simple in its construction, strong and durable, easy to install, thoroughly dependable, not likely to easily become out of order, and otherwise well adapted to the purpose for which it is designed. With the above and numerous other objects in view, as will appear as the descr ption proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will hereinafter more fully be described and claimed.

In the drawing:

Figure l is a side elevation of the governor embodying the features of my invention.

Figure 2 is an end elevation thereof.

Figure 3 is a vertical section through the block of the governor, and

Figure 4 is a detail view of the flap valve.

Referring to the drawing in detail, it will be seen that the numeral 5 denotes a block which is shaped to flt between the carburetor and intake manifoldQand has openings 6' to receive the usual bolts to secure the carburetor and intake manifold together. This block 5 is provided with a passage I therethrough, registering with the passage in the intake manifold. A shaft 8 is journaled in the block 5, and extends through the bottom of the passage 1, adjacent the end adapted to communicate with the intake manifold. This shaft is split in the portion disposed in the passage I for receiving the lower edge of a flap valve 9, which is of such size and shape as to close the passage, but normally inclines toward the carburetor, that is against the flow of the mixture through the passage.

The shaft 8 extends out through one side of the block 5, and secured thereto is a crank III, which extends in an opposite direction from the shaft than the flap valve 9. On this crank ll there is anchored, by means of a bolt or in any' other suitable manner, as at H, a plurality of spring leaves which constitute the multiple leaf spring i2. The leaf of the spring l2 adjacent the crank I0 is shorter than the other leaves, and said other leaves are graduated in increasing lengths. The ends anchored by the bolt II are in contact, but the outer portions of the leaves may diverge from each other, as is indicated in Figure 1.

A plate It is secured to one side of the block A 5, and has an arcuate upper edge with a series of notches or teeth, .as indicated at I. A stop arm I6 is pivoted at its lower end, as at IT, on the plate, and at its free end is provided with a stop projection It. A spring pressed catch I9 is pivoted as at 20 on the arm I 6, and has a lateral member 2| engageable in the notches formed by the teeth [5, the spring 22 being attached to the catch and to the arm. The longest spring leaf is abutablewith the projection II. The shortest leaf is abutable with a stop arm 23, fixed as at 24 to the plate ll.

The valve leans toward the passing air which tends to catch the valve, raise it, and close the passage. As the valve tends to close the passage, it crowds and presses the leaves together against the speed regulating stop arm l8, until their combined resistance equals the pull on the valve which checks the speed of the engine. When the load the engine is pulling becomes greater, the speed of the engine will naturally become slower, if the throttle is not opened. The governor unit is, however, the throttle, and it does open. As the speed of the engine slackens, the suction becomes less, causing less pull on the valve which will consequently be forced open further, by the multiple leaf spring, until their .1 resistance equals the pull on the valve once again.

This action is even and uniform and will maintain an even engine speed.

It can readily be seen that as the surface of the valve becomes less and les angular with respect to the passing of the mixture through the passage, the pull of the valve will gradually become less.

valve as it opens. The action oi the spring in. connection with the valve causes the variable resistance in the passage that controls the engine speed evenly under varying loads..

Obviously, the arm it may be held in dilierent adjusted positions by means oi the catch is, and thus the speed can be flxed as desired. The stop arm 28 catches the shortest leai and prevents the valveirom ialling so low that the suction oi 1 themixture will not catch it. This governor is very emcient. least load variation, and permits the use of all oi the available power of the engine at any speed setting. It does not interiere with the speed or throttle action oi the carburetor oi an automo bile, up to the speed setting at the governor, and then by opening the carburetor governor wide, the governor will maintain an even speed on the road. This governor would be very effective ior delivery car owners who do not want their delivery cars driven over a given speed. The governor is entirely dependable.

It is iree irom parts that are apt to get out of order. It is long lived because there are practically no moving parts. It is simple inconstruction, with no parts to get out of order and it requires no oil and consequently no attention. It is easily installed, requiring no complicated adjustments.

It is thought that the construction, operation, utility and advantages oi. the governor will now be quite apparent to those skilled in this art,

without a more detailed description thereoi.

The present embodiment of the invention has been disclosed in detail by way of example, since in actual practice it attains the ieatures of advantage enumerated as desirable in the statement oi the invention and the above description.

It will be apparent that changes in'the details 01' construction, and in the combination and arrangement oi parts may be resorted to without departing irom the spirit and scope oi the in-v vention as hereinafter claimed, or sacrificing any oi its advantages.. r c
